| 摘 要： | 为防止光缆损坏和断裂，需要对光缆受力情况进行检测。为此对BOTDR（布里渊光时域反射）、BOTDA（布里渊光时域分析）、干涉型、光纤光栅型四种光纤应力检测技术的原理和结构做了介绍，对每种检测技术的信噪比进行了分析，得出BOTDA和光纤光栅型系统的信噪比较大，最后对每种技术的优缺点进行了总结，介绍了各种技术的应用范围。

| Abstract: | For the purpose of preventing the fiber from being damaged and broken,the fiber strain in the cable needs to be detected.There are four main fiber strain detecting technologies: BOTDR(Brillouin optical time domain reflectometry),BOTDA(Brillouin optical time domain analysis),fiber interferometry and fiber grating.The theroy and configuration of these fiber strain detecting technologies are introduced.The signal to noise ratio(SNR) of these technologies are analyzed.The conclusion is that BOTDA and fiber grat... |
